EVIL UNDER THE SUN (1982)
Rewatched this now-classic film with a stellar cast including Sir Peter Ustinov, Roddy McDowall, Diana Rigg and the late great Dame Maggie Smith. In particular, wanted to watch another film with Maggie Smith, seeing her sad passing last year, she will be much missed.
Based on the Agatha Christie novel of the same name, the story is set on an island hence the "locked room" premise that the perpetrator is one of the guests on the resort. Maggie Smith in this adapted screenplay is the proprietress of a slightly-faded hotel & resort, welcoming a number of couples, including a famous and temperamental actress, played by Diana Rigg. Her husband is trying to ignore his wife's brazen flirting with the male guests, and when she is murdered, Poirot has to solve this seemingly impossible mystery.
In particular, I loved the sparring between Diana Rigg and Maggie Smith, when the latter but takes a swipe at her rival saying they were both in a chorus, quipping that "Even in those days, she could always throw her legs up in the air higher than any of us… and wider.". Camp!
Of course, one cannot overlook the starring role played by Peter Ustinov as the detective; whilst not true to the novel's depiction is played with a light touch, and he comes across to me more like one's slightly eccentric uncle... a little odd but overall very lovable, benevolent but with razor-sharp powers of observation.
The director is none other than Guy Hamilton of James Bond fame, and the whole film actually has that glamourous touch and exotic location that hints of that genre. But more sinister than dastardy megalomaniacs and deadly gadgets, it's the equally frightening evil that lurks in seemingly "normal hearts and minds" that plots and puts into motion this fiendish murder.
